Justification:
Listed as Endangered because its Extent of Occurrence is less than 5,000 km2, its distribution is severely fragmented, and there is continuing decline in the extent and quality of its habitat in the Blue Mountains.

It is found in deep woods on streamside rocks and among ground litter; the males call from concealed terrestrial sites. It can only tolerate very temporary habitat disturbance. It breeds by direct development and the eggs are laid on the ground.
